Yes manifolds are stock and are made of a cast, which is very rough in the inside creating a barrier for premium air flow. Manifolds are cheap and easier to make, that's why they use them. Headers are made of tubing which is a smooth surface to create a better path for air flow.

thanks guys. So the difference is what theyre made of not where they go

more so how they are made than what they are made of.

Yeah, they both hook up to the exhaust ports off of the heads.

Also, the term manifold can be used for either intake or exhaust. Being a former Honda guy, whenever I hear manifold, I automatically think intake manifold. I haven't heard it used for exhaust until I got my stang.
